Spradling #1
Terry County · Coroco SE. (Siluro-Devonian) field · Producing · Horizontal · Directional
Spradling #1 (API 42-445-31844) is a horizontal well in Terry County operated by Crey Oil & Gas LLC, completed August 1, 2018 and listed as producing on the RRC schedule.
The RRC has issued 2 drilling permits (amended once) between 1997 and 2014, permitted to 13,000 ft.
It was permitted by Dimmit County Swd, LLC and has since transferred to Crey Oil & Gas LLC on the wellbore schedule.
Completion filings report 11 formation tops, including Yates, San Andres, Glorieta, Clear Fork.
Its lease has reported 105K barrels of oil since January 1998, last reporting in July 2026. The lease carries 2 wells, so these are lease totals, not this well alone.
